It's determined by the height (angle above the horizon) of the Sun, and the physical height of the object throwing the shadow.
The height of the Sun at midday is 90 degrees minus the latitude plus the Sun's declination of the day, which varies by up to ±23.5 degrees through the year.
The length of the shadow is the height of the object divided by the tangent of the Sun's height.
Example, a 6 ft object at 50 degrees north on June 21: height of the object is 6 ft, divided by tan(90 - 50 + 23.5) so the shadow has a length of 3 ft.

Does the length of a sun stick control the distance a shadow moves?
yes the length of the sun stick does control the distance the shadow moves
Why are shadow shorter at midday?
The sun is highest at noon, therefore any shadows are short. When the sun is low, at sunrise and sunset, the shadows will be long.
What did you notice about the shape of the shadow compare to the shape of the object?
The shape does not change, only the length, depending on where the light comes from. Such as on a sundial, and the shadow gets longer or shorter over hours.
Why are shadows shorter in the early morning or at sunset than at midday?
It gets shorter. At mid day it reaches its shortest point, and throughout the rest of the day grows longer. Also, it drifts from west to east. In the northern hemisphere, it points generally north at mid day, swiveling around to the east in the afternoon.
Why does the length and position of my shadow change as i walk towards a lamp post and when we walk away from the lamp post?
The lower the sun in the sky, the longer the shadow. A shadow is always cast in the opposite direction of incident sunlight. When the sun is directly overhead (at noon) the shadow is shortest.
What is the length of your shadow at midday?

Is shadow short or long at midday?
At midday, shadows are typically at their shortest length because the sun is directly overhead. As the sun moves closer to the horizon later in the day, the shadows become longer.
Why your shadow changes during the day?
The position and length of your shadow change throughout the day due to the angle of the sun in the sky. In the morning and evening when the sun is lower in the sky, your shadow will be longer. At midday when the sun is directly overhead, your shadow will be shorter.
Which direction does shadow point at midday?
The shadow points directly south at midday in the northern hemisphere and directly north at midday in the southern hemisphere. This is because the sun is at its highest point in the sky at midday, casting shadows directly opposite the sun's position.
If you were standing under a tree when would the shadow of the tree be shortest sunrise midday sunset?
The shadow of the tree would be shortest at midday when the sun is directly overhead. This is because the angle of the sunlight is most perpendicular to the tree, resulting in a shorter shadow. At sunrise and sunset, the angle of the sunlight is lower, creating longer shadows.
When it is the afternoon your shadow will get?
At midday your shadow will be at its shortest as the sun is closer to being overhead and you block less of its light. As the afternoon progresses and it gets further past midday the sun sinks lower in the sky and your shadow gets longer.
How does the length of your shadow change in the day?
The length of your shadow changes throughout the day due to the angle of the sun in the sky. Your shadow is longest when the sun is low in the sky, typically early morning and late afternoon, and shortest when the sun is directly overhead around midday. This is because the higher the sun is in the sky, the shorter the shadow it creates.
Is a shadow longer at 9pm or midday?
A shadow is typically longer at 9pm compared to midday because the sun is lower in the sky during the evening, leading to longer shadows. At midday, when the sun is directly overhead, shadows tend to be shorter.
What is midday on a sundial?
The shortest shadow on a sundial would be afternoon or Middaay
what causes shadow length?
The length of a shadow is primarily determined by the angle of the sun in relation to the object casting the shadow. Shadows are longer in the early morning and late afternoon when the sun is lower in the sky, and shorter at midday when the sun is directly overhead. The size and shape of the object casting the shadow also play a role in determining shadow length.
When do you see the smallest shadow form and why?
Midday because the sun is right above you.
What is tall in the morning small at midday and tall again at late afternoon?
A shadow.
